PATENT OFFICE.

ALL-BEARI G.

Beit known that I, LOUIS BURG; a citizen pf the United States, residing at Dallas City,

in the county of Hancockand State of Illinois, have invented new and useful Improvements in- Ball-Bearings for Vehicle-Wheels,

- of which the following is a specification.

My invention relates to ball-bearings for understood from the following description hicle-Wheels; and ithas for its object to provide a ball-bearing of the kind-stated inv "which frictional wear of the parts is practicallyeliminated and one embodying sim le,

sti'o and durable means for jpreclu 'ng cas'ua movement of any of the parts with respect to the others andthe consequent locking ofthe'boxto the spindle. 4

Other objects of the invention will be fully andclaims when the same are read in connection with the; accom Idr'awings; Q forming part of this'spec' cation, in which p Figure 1 is a side elevation of the' ball bear H ing constituting the presentand preferred -'embodinient oi my invention. ;:,F-ig; -2 is a --longitudinal sectionof the samewith-the axle-s iiidle inelevaltion.

A; is the axle of my improvements. The

said, axle, is provided with the usual collar c,

j audit is also provided with a tapered spindle b, which tefmmates. at its outer end in a port pnc, threaded in one direction, which porlongitudinfl. and d of the s indleb are'fo'ur equidistant" tion 0 terminates in turn in a reduced portion d threaded in the opposite 'diIG'CiLlOIl, as s own in 2.

This split ring -D 'has for its function to retain the balls f in the cup C,

so as to remove the liability of any of the Specification of Letters Patent. 7 Application 518a December a, 1906.. Serial No. 346,683.

of the bearing B'atented March 12, 1907;

described, is removed from the spindle b.

a E is the axle-box of the bearing. This box is removably arranged on the spindle b and is afforded between the two, and it is provided balls being lost the'airle-bon, presently 6o loosely surrounds the same, so that, clearance p at its inner end witha circular channel, h to '7 bear against the balls f in cup .C and is. also .provided at its outer .end vwith vvaficir cularantifriction-balls of the'bearing in the manner hereinafter .set forth.

6 channel It, designedto bear against the outer F-is the removablecombined cup and nut I This combined device comprises a circular portion Z, which has an inte- 'rior groove m to receive antifriction-balls and also has a fianger at its inner edge, wit

in which is retained a split ring as for retain: ing the balls 1) in the cup ortion and anut portion t, which is interior y threaded, as 111- 4 dicated by a, to engageth e threaded portion 0' of spindle b, and. is 1provided. with three equidistant longitudina grooves 0,1, which interrupt the said thread a, and islalsolprovided in its outer side or face with diametrically-op .z a

the spindle portion d. The key G is designed to be removably placed in oneof the grooves B of the axle-spindle'f 1) and; the particular} groove "b; ofthe 'combined={cup andnutf r-Fgvs movement of the combinedciip and nut on 5 the spindle; which would be; liable" to lock the box IE to the spindle and cause-injury to the I bearing as a whole:' In' this'conne'ction'it will be noticedthat the rov-isi'on of the four longitudinal grooves B eaves ample surface for the formation of .the threads c and-d and rio.

that the combination of the three equidistant grooves 12 in. the combined cup and-nut F I 'with the Tour eduidistant grooves in' the spindle admits o the operator 1/ 192 inch adjustment when sixteen threads to the mob are employed without impairing the strength of the spindle and the combined cup and nut, and this notwithstandin the fact that the key preferably employe is threesixteenths of an inch in diameter. 1 j In the practical use ofmy improvements the box E is arranged on the spindle b and so that the channel h at itsinner end bears against theinner balls f, after, which the comb ned cup and nut- F is turned .on the threaded portion a of the spindle until its balls p bear against the channel I: at "the -outerjend of the box E. The key G is then shoved home in opposed longitudinal grooves of the spindle and combined cup and nut,

after which the cap-nut H is turned'up on the reduced and threaded end portiond of the indle' b until its inner end abuts against this done it will be apparent that casual -mov'emcntof the combined cup and nut-E on but a will also the same may be quic' plished after the cap-nut H, the key G, and the combined cup and nut F,'-are removedy the spindle is precluded, and hence there is 4 no liability of said combined cup andnut becoming casually set againstthe box E and in that way l00kl1lfhfiflidb0ri to the spindle; e apparent" that when it is desired to remove the ox E and the wheel in which'the sameis arrarigedfrom the spindle b yand easily :accomfrom the spindle 1n the ordernamed.

- It ll be gathered from the foregoing thatl when iny'fnovel ball-bearing is in use the Box .E b:6il1"S j &'B.ln Sli the :inner and 'outer anti-- 7 friction-balls alone,wi th the result-that there; 40

is absolutely no fr ctional wear between the;
